This invention relates to building construction employing steel beams or uprights and pre-cast or fabricated wall units, and my improveinent is directed to means whereby the uprights and'wall units are unitedrand interlocled in such'manner as to producean ino tegrated building structure of homogeneous texture that cannot be disrupted by climatic, seismic or other influences to which buildings are subjected. Y

Briefly expressed o my improved building construction consists of suitablyspaced ver- `tical I beams composed of Steel, mounted on a suitable foundation andy provided with the i usual horizontal beams. v

yPlaced against these vertical beams are panels, compo-sed of cast material, such as concrete -with wire reinforcement and an outerlinisli, said panels having' cast therein vertical steel rods carrying eye-bolts that project from the inner surfaces of the panels. t is by means of these eye-bolts, whichv are providedwith securing` devices, thatthe panels are rigidly clamped into permanent, interlocked engagement with the vertical steel. I beams, thereby constituting an integrated wall structure of unusual strength and durability.

I have found it desirable to employ a light weight concrete for the wall panels, such for example as Ciiidker concrete, and by reason thereof and of the secure union edected bescale of a vertical I beam, also showing la wall l l panel united therewith.

Fig. 3 is a section on the line 3 3 2, and o y Fig. 4 is a frontelevation of a wall panel. 1 In said figures let 1 indicate the vertical I beams employed in my improved wall construction. lVhile some of said beams 1 in Fig.

lof Fig.VV

l are shown as of smaller cross-section than others it is essential that the flanges of all ik said beams opposed to the wall they support are disposedin the same vertical plane.

At 2 I have indicated wall 4 formed of suit- Y able cementitious composition in'which is einbedded metallic reinforcement lying in a plane parallel with 'the panel surfaces. EX- terior finish of any suitablecharacter may be applied tothe outer surfaces of the panels. lIii-the example illustrated I have shown tiles 6, spaced apart and having opposed bevelled n edges, so that the cemetitious material ofthe panel may be inouldedbetween said edges to comprise dove-'tailed interlocking joints.

Also embedded in the cenient-itious niaterial of which the panels are composed are vertical steel rods 7, and threadedv on said rods are eye-bolts 8 whose screw portions 9 project out beyond the inner surfaces of the panels. Washers or disks 10 are placed upon the screw port-ions 9 of the eye-bolts and are adapted to-engagefthe flanges 10 of I beams lv that lie against the inner surfaces of the panels. As thus positioned,nuts^1l, engaging Ascrew portions 9 are screwed tightly against thewashers causingkthe latterto securely clamp the I beam flanges againstthe panels. It is in this manner that the vertical I beams and the wallpanels become integrated in the formation of a homogoneous wall structure.

Variations within the spirit and scope ofi my inventionare equally comprehended by the foregoing disclosure.

I. claim; o n In building construction including a plurality of vertically disposed and spaced apart I-beams, panels attached to the flanges of. said I-beams, each of said panels including embedded eye-bolts having their Vthreaded prtons projecting beyond the rear face of said panel, rods extending vertically through said panel and passing through the eyes of said eye-bolts and means for securing said bolts to the flanges of said Lbeams, said means in cluding Washers thatoverle the marginal edges of said flanges.
